Struct BatchTaskFailure 

pub struct BatchTaskFailure<E> { /* private fields */ }

Failure record for one task inside a batch.

Each failure keeps the task’s stable batch index so callers can map the failure back to the source task.

use qubit_batch::{
    BatchTaskError,
    BatchTaskFailure,
};

let failure = BatchTaskFailure::new(2, BatchTaskError::Failed("invalid row"));

assert_eq!(failure.index(), 2);
assert!(failure.error().is_failed());

Type Parameters

• E - The task-specific error type.

Implementations

impl<E> BatchTaskFailure<E>

pub fn new(index: usize, error: BatchTaskError<E>) -> Self

Creates a new batch task failure record.

Parameters

• index - Zero-based task index within the batch.
• error - Error observed for the task at index.

Returns

A failure record containing the task index and error.

pub const fn index(&self) -> usize

Returns the failed task’s zero-based batch index.

Returns

The task index recorded for this failure.

pub const fn error(&self) -> &BatchTaskError<E>

Returns the task error recorded for this failure.

Returns

A shared reference to the task error.

pub fn into_error(self) -> BatchTaskError<E>

Consumes this failure record and returns the stored task error.

Returns

The task error previously stored in this failure record.

Trait Implementations

impl<E: Clone> Clone for BatchTaskFailure<E>

fn clone(&self) -> BatchTaskFailure<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: Debug> Debug for BatchTaskFailure<E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E: PartialEq> PartialEq for BatchTaskFailure<E>

fn eq(&self, other: &BatchTaskFailure<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
